Psychological safety is a shared belief within a team that it is safe to take interpersonal risks: to ask a question, raise a concern, admit a mistake or disagree without being embarrassed or punished. The team-level concept was developed by Harvard Business School professor Amy Edmondson, and it is a property of a team, not of an individual.
What it is, and what it is not
Psychological safety is not niceness, comfort or the absence of conflict. A psychologically safe team can argue hard about the work precisely because nobody expects to be humiliated for being wrong. Nor is it lowered standards: the most effective teams combine high safety with high accountability. Low safety with high standards produces anxiety, and people hide problems until they become expensive.
Why it matters
Teams with low psychological safety lose information. Errors go unreported, questions go unasked and the person closest to a problem stays quiet because speaking up feels risky. It gets close attention in healthcare and aviation, where a concern nobody raised can be a safety incident. In Australia, work health and safety law now requires employers to manage psychosocial hazards like any other risk, and a team where people cannot raise problems is a team where those hazards stay hidden.
How to measure and build it
Measure it at team level, with questions about whether people can raise problems, ask for help and take a risk without it being held against them, and compare teams rather than reading one company score. The biggest lever is usually the team leader: how they respond to bad news, whether they admit their own mistakes and whether they ask for input before deciding.
Where Compono Engage fits.
Compono Engage is an employee engagement platform that reads culture and climate alongside work personality, team by team.

They are related but not the same. Trust is about how one person sees another. Psychological safety is a shared belief across a team about how the group will respond when someone takes a risk.
Can one person create psychological safety?
A team leader has the most influence, because the team watches how they respond. But it is built or broken by everyone's reactions over time, which is why it is measured as a team property.
